Nude photos of X Factor judge Demi Lovato have reportedly surfaced online. The collection includes 20 photos of a woman who appears to have the same tattoos as the singer.

RadarOnline claimed Monday that it has these photos, but decided not to publish them. They show a dark-haired woman in a bathtub, lying topless on a bed and in other sexually suggestive poses. However, the site notes that it couldn’t verify 110 percent that these show Lovato, but the woman has tattoos that look similar to hers.

“These are Demi,” a source told the tabloid site. “The collection I have show some nude, including face, some including parts of the body Demi is known for — tattoos, butt, chin. Then, I have pictures of her getting rowdy… I can guarantee you these photos are legitimately of Demi.”

It’s not known if these photos were leaked by a hacker, similar to what happened to Scarlett Johansson, Mila Kunis and others.

Lovato and her rep didn’t comment. She’s currently getting set for the new season of The X-Factor. TV Line also reported today that she’s secured a recurring spot on Glee.
